I didn't realize how old it was. Im new to the group and was just reading everything. My apologies. Won't happen again.
That looks bad and a vet would be your only answer I am thinking at this stage. Is this right outside her vent if so It's a prolapse which means her insides are hanging outside.My female muscovy duck has had this giant fluid filled sack beside her vent, and has not eaten or drank anything in 5 days. She had 2 eggs in the yard. She can't really walk anymore. She is shaking uncontrollably. It Is not an egg, it is mushy and fluid filled like. I let her sit in warm water twice and I'm not sure what to do. Please help, I feel really bad for her, seems like she's on her last breath.
